What Kind of Atheist are You?

[Red Economist]

Communism is not a type of atheism; it is a worldview that incorporates atheism as one of its components.

Communism is an socio-economic system. It embraces atheism as an adjunct.

Marx's philosophy was directly inspired by Ludwig Feuerbach's "The essence of Christianity" in which Feuerbach argued that man created god, and god was the alienation of man's being a god was the projection of human qualities and so is inherently atheist. Philosophical materialism, and therefore atheism as the rejection of the ability of consciousness to exist independently of matter/the body, is the most fundamental assumption on which virtually all communist beliefs are built. Communism is a worldview, and is unquestionably a logical conclusion of a certain form of atheism; the non-existence of god and the supernatural is the basis for believing that the natural and social world can be mastered consciously by human beings.

I'd say that- as a worldview- it is a type of atheism distinct from secular-liberal forms of atheism (such as the 'New Atheism'), but yeah, that is not true of all forms of communism (some of which are religious).
